One of the 13 puppies seized in a drug raid remains in poor condition, but the rest have bounced back after a 24-hour stint with David Johnson, owner of Middleboro Veterinarian Clinic.

“That little one wouldn’t have made it through the night,” Johnson said of the weakest pit bull that is weighing in at just over a pound. “We’re still worrying about this one.”

He said the tiny pup still requires ’round-the-clock care. His heart isn’t pumping correctly because the internal organs were shutting down, and Johnson said he is worried the dog suffered internal damage.

The litter was delivered to Johnson emancipated, dehydrated, dirty, covered in feces and riddled with worms on Wednesday. They were all weak and starving,

“They have no fat, nothing,” Johnson said. “Boy, they had appetites.”

Overnight, the rest of the litter bounced back after being fed, wormed and bathed.

“It was almost miraculous; they’re lucky dogs,” Johnson said. “Too bad the only thing that saved them was a drug bust. It was a bad state of affairs.”

Johnson said the pups are coming along nicely, “but still they’re little bone racks.”

The puppies are between 4 and 5 weeks old and have been placed in foster homes until they are ready for adoption. But the littlest could remain with Johnson forever, “If it gets better, it may remain here. We’ll see; time will tell.”

Johnson just might have his hands full with another litter. He said one of the four adults that was seized might be pregnant.

Johnson said the owner, John Campbell, signed the dogs over to the town after he was arrested in a drug raid Wednesday.
